Abstract
The utility model relates to a casting chute used in metal casting in the metal smelting process, in particular to an improvement of a casting chute structure in the silver smelting process, and discloses a silver casting chute. The silver casting chute is characterized by structurally comprising a graphite-manufactured inner layer arranged on the inner layer, and a ramming material layer coating the graphite-manufactured inner layer. The silver casting chute is manufactured in the mode that graphite is used for forming and ramming materials are used as the outer lining, overcomes the shortcomings of a traditional ramming material chute, can meet the requirements of various kinds of metal casting, has the advantages of being long in service life, safe, capable of saving energy and the like, is easy to operate and maintain, and has wide promotion value in the metallurgy field.
Description
Technical field
A kind of silver casting chute relates in a kind of metal smelt process, casting of metals casting chute, the particularly improvement of silvery white smelting process casting chute structure.
Background technology
In smelting process, the chute in silver-colored casting field generally adopts the mode of ramming mass knotting moulding to make, and this chute is subjected to influence of temperature change bigger, and chemical stability is low, easily washes away and peels off, and adheres on the silver anode plate, influences silver anode plate quality.Chute surface by the ramming mass moulding is more coarse, be easy to make silver to be bonded in the surface, and silver is hot good conductor, setting rate is fast, and in casting cycle, silver-colored liquation rapid condensation is on the chute surface, cause chute to stop up, casting can't be carried out continuously, the solidified superalloy of the cleaning chute interior that can only stop to cast, scale removal process has great mechanical damage to chute, therefore, having reduced chute service life, only is the 2-3 heat, do not satisfy the quantity-produced needs, increased the cost of overhaul simultaneously.
Summary of the invention
The purpose of this utility model is exactly that pin is unraveled silk the deficiency that above-mentioned prior art exists, a kind of have good thermal conductance and heat-resisting quantity are provided, thermal coefficient of expansion is little, and anxious heat, chilling are had certain anti-strain property, has the silver casting chute of excellent chemical stability.
This practical purpose is achieved through the following technical solutions.
A kind of silver casting chute is characterized in that its structure comprises the graphite that is positioned at internal layer internal layer processed and is overlying on the outer ramming bed of material of graphite internal layer processed.
A kind of silver casting chute of the present utility model is characterized in that dashing the chute end at place under silvering solution, be provided with a buffering pit that is lower than the chute inner groove surface.
A kind of silver casting chute of the present utility model at the deficiency of traditional chute, on the analysis and research contrast basis to ramming mass and graphite material, adopts chute and the matching used device of ramming mass of graphite material.Graphite has good thermal conductance and heat-resisting quantity, in the high temperature use, thermal coefficient of expansion is little, anxious heat, chilling had certain anti-strain property, corrosion resistance to acid, alkaline solution is stronger, have excellent chemical stability, and ramming mass have good heat-insulating property and heat-resisting quantity.Use the graphite chute to add ramming mass, because the graphite resistance to elevated temperatures is good, can bear washing away of high temperature silver liquation, reduced impurity and entered in the positive plate, the graphite chemical composition comes impurity can for the silver anode strip simultaneously, has promoted anode plate quality; Graphite chute smooth surface is smooth, does not adhere to silver, has guaranteed that chute is unobstructed, has improved single stove operating efficiency; The graphite chute adds ramming mass, has guaranteed chute temperature stabilization in process of production, and silver-colored liquation can not condense, and has ensured to produce to carry out smoothly, has also saved the energy resource consumption that chute heats up.Chute adopts the Fast Installation mode, and the easy access operation has improved operating efficiency, has ensured the safety and steady operation of producing;

The specific embodiment
A kind of silver casting chute, its structure comprise the graphite that is positioned at internal layer internal layer 1 processed and are overlying on the outer ramming bed of material 3 of graphite internal layer processed; Under silvering solution, dash the chute end at place, be provided with a buffering pit 2 that is lower than the chute inner groove surface.
During making, adopt graphite to make the chute shape, empty out the buffering pit in graphite chute end, carry out ramming at the outside ramming mass that adopts of graphite chute, form thermal insulation layer, guarantee that the chute interior temperature can not rapid diffusion, reach the thermal isolation and heat storage effect, simultaneously the buffering cavity of graphite chute has effectively alleviated washing away of silver-colored liquation, has prolonged chute service life.
Claims (2)
1. a silver casting chute is characterized in that its structure comprises the graphite that is positioned at internal layer internal layer processed and is overlying on the outer ramming bed of material of graphite internal layer processed.
2. a kind of silver casting chute according to claim 1 is characterized in that dashing the chute end at place under silvering solution, be provided with a buffering pit that is lower than the chute inner groove surface.
